It was pretty straight forward STAR method behavioral question.
I think that if you just google STAR method interview you will find really good information.
Just make sure you have a couple of stories of what you accomplished or went through and you should be fine.
Also I think that you should definitely ask questions at the end of the interview. They really like candidates that ask questions at the end, so research some and ask.
Application process might take a while. For me it took a really long time to hear back, but do not hesitate to email asking for a status update. Just make sure you are not emailing everyday or something,
